Compare the two and pick the one that suits your preferences.
Solvent I have never had to wear gloves to print or perform standard maintenance (Mutoh, Mimaki, Roland and Vanguard certified repairman).
Solvent heads cost more per head, but over the life of a Latex Printer you replace heads every 4 to 6 cartridges at 125 per head.
Solvent runs on 110 volt power (one or two 20 amp circuits based on single head or multi head printer).
Latex use 2 220v circuits.
Look at print speeds if production should be one consideration.
Also look at the new UV roll printers, Roland and Mimaki have them.
I guess what I saying is make a list of your requirements. List everything you can think of, cost of operation, print speed, maintenance (is there a tech close), also under maintenance, consumable costs (print heads dampers, cap, pump, encoder, etc..), print quality (ability to match if needed prior printing).
Don't let others tell you one is better than the other, THEY ARE DIFFERENT, each has it's own set of issues, pick the one that best suits your requirements.
